URINAL.

`SIPIE|CI1 `ICATI0N forming part of Letters Patent No. 761,278, dated May 81, 1904.

i Application filed August 24, 1901. Serial No. 73,194- (No model.)

To all whom t may concern/l' Be it known that I, HENRY M. WILLIAMS, a citizen of the United States, residing at Fort Wayne, in the county of Allen and State of Indiana, have invented certain new and useful Improvements in Urinals, of which the following is a specification.

This invention relates to urinals, and is an impnovement on the apparatus shown in the patent issued to Franz Burger and HenryM.

/Villiams July 10, 1900, No. 653,437.

The object of the invention is to provide simple and effective means for flushing automatically the grating on which the person stands after the person leaves the grating.

The invention will be fully described hereinafter, reference being had to the accompanying drawings, in which- Figure 1 is a side elevation partly in section. Fig. 2 is a sectional view through the valve and valve-operating mechanism. Fig. 3 is a front elevation, the upper part being broken away. Fig. 4 is a side elevation with the grate in section, the upper part also being broken away. Fig. 5 isa cross-sectional enlarged view of the flushing-pipe and part of the grating.

In using urinals of the class described in said patent the grating is liable to become soiled and wet from the dropping of urine, which is objectionable, not only for the reason that a disagreeable odor is created, but also that the soles of vshoes may become soiled and in their turn soil floors or carpets. A rinsing or Washing of the grating after each use of the urinal will overcome these objections, and it is to accomplish such rinsing or washing automatically that I have made the present invention.

The grating 1 is hinged on a perforated horizontal pipe 2 and held in an inclined position by a bell-crank lever 3, which is fulcrumed at the iioor. One arm of the lever 3 rests under the free end of the grating 1, and to the other arm is attached a chain 4, running under the guideroller 5 up to the arm 6 of an angle-lever in front of a valve-chamber 9. This lever is fastened at its elbow to a horizontal shaft 8, journaled in the valve-chambers 9 and 10, and its other arm, 6, is provided with aweight 20. The chamber 9, which incloses the valve controlling the flushing of the urinal-basin, need not be described herein, as it is fully described in the patent above referred to. rIhe shaft 8 projects from the chamber 9 into the chamber 10, and on the shaft 8 revolves loosely a ratchet-wheel 11. Next to the ratchet-wheel and in the chamber 10 an arm 12 is fastened to the shaft 8, and on the outer end of arm 12 is pivoted a pawl 13, engaging the teeth of the ratchet-wheel 11. Below the ratchet-wheel a valve 14 is located, and the upper end of the stem 15 of this valve is beveled and projects between two teeth of the ratchet-wheel 11. A spiral spring 16 yieldingly holds the valve to its seat and also yieldingly holds the beveled end of the stem in engagement with teeth of the ratchet-wheel. The water-supply for this valve is takenfrom the main Water-pipe by the pipe 17 and when a valve 14 is depressed the water passes by the valve 14 to the pipe 18, which connects with the perforated pipe 2. In this pipe 2, Fig. 5, three rows of perforations 19 are shown, and each row is drilled at a different angle to insure spreading of the water over the whole grate-surface.

The working of the apparatus is as follows: When a person steps on the grate 1, the grate is depressed, which operates the bell-crank 3 and the chain 4 to pull down the short arm 6 of the angle-lever and raise the weighted arm 6a. The shaft 8. and its arm 12 and pawl 13 are also operated'by this movement, the pawl 13 being moved over one of the teeth of the ratchet-Wheel to engage another. As long as a person remains on the grating 1 the weighted arm 6 is prevented from dropping; but as soon as the person leaves the grating the weighted arm 6 begins to fall, the shaft 8 commences to turn, and the pawl 13 imparts motion to the ratchet-wheel and revolves the same one tooth. The valve-stem 15, which is in close contact with the teeth of the ratchetwheel, is thereby depressed, opening the valve 14 for a short period, or as long as it takes one tooth to pass over the end of the stem. The water will iiow down the pipe 18 into the horizontal pipe 2 and out through the perforations 19, thereby rinsing or washing the whole surface of the grate. Means will be provided whereby the waste water may be carried to the waste-pipe.

Without limiting myself to the precise details of construction and arrangement of parts shown, I claim- 1. The combination with a grating, of a perforated pipe upon which the grating'is hinged, a valve to Control the flow of water to the perforated pipe, and means controlled by the movement of the grating to operate the valve, substantially' as set forth.

2. The combination with a grating, of a perforated pipe to sprinkle water thereon and upon which the grating is hinged, a valve to control the flow of water to the pipe, a stem projecting from the valve and having a beveled end, a ratchet-wheel with which said beveled end engages, and means controlled by the movement of the grating to turn the Wheel and thereby open the valve, substantially as set forth.

3. The combination with a grating, of a perforated pipe to sprinkle water thereon and upon which the grating is hinged, a valve to control the flow of water to the pipe, a stem projecting from the valve andy having a beveled end, a ratchet-Wheel with which said beveled end engages, an angle-lever adjacent to the ratchet-wheel and having one arm weighted, a pawl movable with the lever and engaging the ratchet-wheel, and a flexible connection between the unweighted arm of the lever and the free end of the grating, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subsoribing witnesses.

HENRY M. WILLIAMS.
